Original application filed ()ctober 23,

To all wkom it may concern.-

. Be it known that I, Josrrn E. limxnoi',

' a citizen of the United States, and wresiticnc of the borough of Manhattan, city, county, and State of New York, have invented cer tain new and useful Improvemens in Gyrw.

tory Crushing Apparatus, of which ihe fol: lowing is a specificationf The present application is a division of that filed by inc Get. 23, 1917, Serial No. 198,023, and relates more particularly to the means provided for the lubrication of the eccentric bearing in which the lower part of the gyratory shoftfis ,m0lln lBfi,i3hfs invention consisting in the specific construction and arrangement 7 of parts described and claimed, and :1 distinctive feoun'e hcing the method whereby a forced cilflllfifilQK] of tho lubricant is positively and automatically at tained, and a supplyv thereof to the top of v the bearing assured, all as heroinzaiicr more Feb, 3, 19 rch 1?, 1 1i, a Ne wry cruior so which mypresein: monks are especially cp hcable. Thus ighe tmnczifoed conical crushing: hood a is Figfully self, forth.

The accompanying drawing a cemroi vertical sectional devotion of a gyraimy crushing apparatus to which my lubricating;

system is appliexl.

In general charactcristics'ihe apparcins illustrated in the drawings is primariiy the same in principle and operation as set forth in'Letoers Patent No; 1,085,865, issued to me No. 1,090,2'ifi, lSSEKii to me .iJWSJEMi, issue. to me March 526, 1916, to which reference may he had as showing the type of gyro.-

of ihe m g pic-fie C, as shown in the drawl!ig?3,- hing 6 being interposed vetwecnthe hub c, anci the hearing slecvc a. To the ugmer port, of this eccentric hearng siceve e, is rigidiy secui'cd,'as ov the lrcy c, io the driven pulley e, by \i'hich said sieeve a, is rotated to impart a gyraiory rotation to the shaft ihr'ough the medium of the aforesaid eccentric hearing (2, the operziion and functions of which latto? are clearly set, forih in the Letters imy out heroinheioro referred to, particularly Lowers Zatent lilo. 1,176,833, the meansfor effecting the liihricaiing" circniation being essentiaily the some as disclosed in that pat- 79' enfi errccpt that in the prlm'ni', case I supplomcnt ilie autonomic system oi lubrication by positive means for transfen'ing the lubricant from the exterior of ihe rotaluahle siecve c, to the interior thereof. Tho sleeve 6', is; formed with an annular no e a", by which it is rohiiohi jr supported on the ioner casing or hoiionrpiote g, o floating ring 8. being interposed between said annular flange e, and the actual rest or seat. 9 f'iim'ounding fhc scat g, is an annular gutter to receive the oil which passes out around ,the heating ring 8. The bottom of ihis annular gutter is inclined as indicated by she domed Zinc 51, to conduct the oil thus received into a cckcfi 5/ from which the oihis returned in wart through the Lin-ct. to no space in the casing be-' low the shafi, imaging, and siwve, to again porcoloie ixpiviirdi by capiiiary attraction between the opposed surfaces to he luhiiccied, as set foiih in said Letters Patent No. 1,176,853. The rotation of'ihc aris thus insures on automatic simulation of the oil which is most, eii'eciive for heir lu'hricaiiflii. in onicr however to positively insure a supply of iuhricinting oil the sleeve '8', above the QCOJTii-I'K: hearing 6, zmrl thereby oiiect a gravity food to said hearing 6, 0 snppiement ihe upii'erduipiiiary feed to the annular goiter 5/ I abstracta portion of the nii from the pocket 9 by means of the pipe 11, leading hi) the pump P, by which it. is returned by the pipe 11', through the iii/er 1)", to the sleeve 6', as imiimted in the drawing. his utilization and combination oi both capillary ami gravity afiiz'aciion obviates all danger of injury from lack of lubrication throngh failure of ample supply of oii to the comrnciing surfaces and safeguards the apparatus in this respect against carelessness or indifference on the part of attendants.

,ing sleeve 6. Thearp-per end of the latter is closed by a dust guard it, and the inlet pipe 1), from the pump P, may enter the said sleeve 2 through said dust guard h,

shown. it, is a dust guard which closes the opening in the upper part of the drive chamber in the usual manner.

What I claim as my invention and desire to secure by Letters Patent is,

1. In crushing ap aratus of the character designated, the com ination with the gyratory shaft, eccentric bearing, rotatable sleeve, and casing therefor formed with an annular utter for the collection of oil raised by caplllary attraction and with a return conduit. connecting said annular gutter with thc lower part of the casing, of means conncctcd with said return conduit for positively transferring oil therefrom to the eccentric sleeve above the eccentric bearing, for the purpose described.

2. In crushing apparatus of the character designated, the coniliiination with the gymconnecting said annular tory shaft, eccentric bearing, rotatable sleeve, and casing therefor formed with an annular gutter for the collection of oil raiscd by capillary attraction and with a rcturn conduit gutter with the lower part of the-casing, of means connected with the casing for positively transfcrring oil therefrom to the eccentric slccvc above the eccentric bearing, for the purpose dcscribed.

3. In crushing apparatus of the character designated, the con'ibination with the gymtory shaft, eccentric bearing, IUttttflbli: sleeve, and casing therefor formed with an annular gutter for the collection of oil raised by capillary attraction and with arcturn conduit connecting said annular gutter with the lower part of the casing, of means connected with the casing for positively transferring oil therefrom to the eccentric sleeve above the eccentric bearing, said means including a pump operated by motion derived from the said rotatable eccentric sleeve, for the purpose described.

4C. In crushing appa 'atus of the character designated, the combination with the gymtory shaft, eccentric bearing, rotatable sleeve, and casing therefor formed with an annular gutter for the collection of oil raised by capillary attraction and with a return conduit connc :ting said annular gutter with the lower part of the casing, of means connected with the casing for positively transferring oil therefrom to the eccentric sleeve above the eccentric-bearing, said means comprising suitable piping, a pump interposed therein and operated by a pulley, and an' endless belt driving said pulley and pump by motion dcri'vcd from the rotatable eccentric sleeve, for the purpose set forth.
